摘要
作为一种电极材料或电极修饰材料，PEDOT：PSS薄膜常用于有机光电器件领域的应用研究。然而，较低的电导率（≤0．8S／cm）与酸性（pH=1.5～2．5）已成为限制PEODT：PSS薄膜在上述领域进一步应用的瓶颈，因此，PEDOT：PSS薄膜性能优化正在成为一个新的研究热点。文中综述了近年来PEDOT：PSS薄膜性能优化研究的新进展，着重论述了有机物掺杂、无机物掺杂、热处理、紫外／臭氧处理、氧等离子体处理以及外加电场等多种方式对PEDOT：PSS薄膜电／光性能的优化效果及相关机理研究。同时，文章对PEDOT：PSS薄膜性能优化研究工作中存在的焦点问题亦进行了客观分析与评价，并探讨了未来研究重点。
As an electrode or electrode modified materials, films fabricated from commercially available poly （3,4-ethylenedioxythiophene） （PEDOT）：poly （4-styrenesulfonate） （PSS） aqueous dispersions were widely used in modern organic optoelectronic devices. However, the film also suffers the low conductivity （≤0.8S/cm） and the acidity （pH=1.5～2.5）, which are main limiting factors for the practical application. Therefore, the optimization of film properties has attracted a lot of attention. In this review, the new developments in the properties optimization of PEDOT： PSS films were summarized. More attention was paid to the improvement of PEDOT： PSS film properties by some especial treatment, such as organic doping, inorganic doping, thermal treatment, UV-ozone treatment, plasma treatment and high-electric-field treatment. Moreover, the mechanism of the performance optimization for PEDOT： PSS films were also mentioned. Finally, the confused problems and prospects of the research on the optimization of PEDOT： PSS film properties were commented.
